Application filed .Tune 30, 1904.. Serial No. 214,701.

T0 all whom it may concern:

Be it knownthat I, CHESTER CoMs'rooK, a

citizen of the United States,residingin Brooklyn, in the lcounty of Kings and State of New York, have invented `certain new and useful Improvements in Lubricators, of which the following is a specification. i This'invention is directed to the art of lubricating, and comprehends the admixture of one material with another,whereby both may be .discharged to theparts to be'lubricated in a compound form.

The invention further comprehends the construction of such devices or apparatus as will automatically accomplish such admixture and to do so preferably bya process resulting in the final discharge ofthe lubricant, and which discharge may be effected by pressure or gravity. v It is comprehended that the results to be obtained may be effected through the instrumentality of various constructions which may be suitably adapted for the purpose specified, and it will therefore be understood that the constructions illustrated on the accompanying sheets of drawings, together with the detailed description thereto appertaining, shall not be considered as confining my invention to the particular form of mechanism or apparatus herein illustrated and described.

It is an object, among others, of the invention to provide any suitable structure which is capable of carrying forth an idea of feeding a lubricant by a gradual discharge and so directing such discharge through another lubricating substance that both of lsaid lubricants may be combined and finally discharged in compound form with that degree of simplicity and efficiency as will render the device practicable and desirable. s

An embodiment of the invention is illustrated by the accompanying sheets of drawings, whereon- Figure 1 is a plan view of an improved lubricating apparatus, portions of which are broken away so as to disclose its construction and the apparatus being shown is applied to a journal-bearing. Fig. 2 is a sectional view in elevation of the same. Fig. 3 is an elevational view of such lubricating apparatus, the

same being similar to that shown in Eig. 2

l with the exception of that portion partially broken away, which is slightly changed Ifor adaptation to a valve-chest of al cylinder. (Not shown.) Fig. 4: is a plan sectional view showing the wire-cloth lining disposed upon a frame which is inserted into the apparatus, and Fig. 5 illustrates a modified form of a lubricating device.

Throughout the various figures similar characters of reference apply to similar parts.

As has been remarked that inasmuch as the principle of this new invention-that is. the conduct of one lubricant into another, then kdischarging both in a mixed or compound state-is capable of being embodied in a variety of devices, I have, for example, illustrated a device applied to a journal-bearingfor instance, as shown in Fig. 2-and to an exhaust-pipe of a cylinder in another instance, as shown in Fig. 3, and in the third instance I have shown a device capable of being applied to various elements of machinery, &c.,

where the other illustrated devices may not be so well adapted for application. 1 In either case it will be observed that the invention primarily comprehends the provision of a reservoir adapted to contain a lubricant, a receptacle for containing another lubricant, means for introducing one lubricant into the other, and a sight whereby it may be determined the amount of lubricant used.

Referring now to the construction shown in Figs. 1 and 2, A6 indicates in a general way a reservoir which may be made in any suitable manner and which in the present instance may comprise upper and lower cylindrical sections 7 and 8, respectively, each of which may be screw-threaded exteriorly, as at 9 and 10, so that they may be fitted into a frame or bracket 1l, internally screw-threaded-at l2 Yand 13 to receive the screw-threaded portions 9 andl() -of said sections, said bracket in the present IOO extension 14, and which, if desired, may be integral therewith, is a steam-chest 17 which is provided with a removable plug 48, preferably screw-threaded into the mouth of said chest, as at 148, and whereby said chest may be tightly closed when the device is in operation. Within this chest 17 and preferably stepped into the wall of the extension 14, is a receptacle 18, provided at its bottom with an opening 19, adapted to register with a conduit 20, which passes through the extension 14 and the bearing 15 and communicates with the opening in which the journal rotates.

' The chest 17 in the present instance may be cast integral therewith, it being undestood that the frame 11, extension 14, chest 17, and extension 21, if desired, may be cast in one piece for cheapness of manufacture. Said extension 21 is provided with a bore which is internally screw-threaded, and passing from said bore to the interior of the chest 17 through the wall of the extension 21 is a port 22, to which in the present instance is attached a nozzle 23, directed into the mouth of the receptacle 18, located in said chest 17.

The extension 14 in the present instance may be provided with a conduit 24, extending longitudinally and inwardly through said extension and to which is connected at 26 an elongated perpendicularly-disposed pipe 25, which extends upwardly in the reservoir 6 preferably to a point very near the top of said reservoir.

The extremity of the conduit 24 communicates with a'nozzle 27, which in the present instance is stepped into a seat 27 O in the extension 14, and this nozzle extends upwardly into a glass tube or sight 28, which is mounted on a packing-ring 29, located around said nozzle 27, and whichl glass tube extends upwardly and communicates with the bore of the extension 21, whereupon the same may bc secured in place by metallic gaskets 32 and 33, a packing 31 being interposed between one of said gaskets and the top of said tube for the purpose of preventinglealrage. A plug 47 is screw-threaded into the bore of the extension 21, and thus, as is obvious, a complete airtight communication is obtained between the reservoir 6 and the journal 16 through the pipe 25, the conduit 24, the tube 28, the nozzle 23, and the conduit 20.

The interior of the receptacle 18 is lined, preferably, with gauze, wire-cloth, or other open-mesh lining 45 and is filled in the present instance with some suitable lubricating compound 46such, for instance, as graphite-which lies in said receptacle in a nonliquid mass, as seen in Fig. 5, upon which may be discharged a lubricant from the nozzle 23, as will be more fully explained hereinafter.

From a suitable source of supply and coming through the conduit 34 is steam, which passes through a transversely-disposed conduit 85, which extends through the wall of the reservoir 6 and conducts the water of condensation down into and near the bottom thereof, it being understood that for convenience and economy such steam may be obtained from any suitable source.

For the purpose of causing the pressure in the reservoir 6 and the chest 17 to be equal I provide a second conduit, 35, which communicates with a conduit 36, entering into a conduit 37 and which communicates with openings 360 and 361, which enter through the bottom of the chest 17, causing such chest to be filled with steam, whereby pressure will be so directed onto the graphite as to prevent it from being lifted out of the receptacle by under pressure through the port 19.

The steam directed through the conduits 34 and 35 will .be condensed into water 38 in the reservoir 6, and such condensation will have a tendency to fill said reservoir. Through the opening 43 in the top of the reservoir` which is provided with a closing-plug 44, I pour oil 42, which rests upon the water resulting from condensation. The glass tube 28 may also be provided with a suitable amount of water 40 for purposes shortly to be explained.

As the process of condensation takes place and the drip passes through the pipe 85 the water resulting therefrom will cause the oil which is borne on its surface to rise, and when the oil reaches the mouth of the pipe 25 it will course down into the conduit 24, which will gradually lill as the condensation continues until it reaches the mouth of the nozzle 27, when the drops 51 of oil will be expelled from said nozzle upward through the Water 40 until it reaches the surface thereof, when a second mass of oil 52 accumulates on the top of the water in the tube 28 until it reaches the mouth or level of the port 22, when it will commence to run through said port into the nozzle 23 and drip onto the mass of graphite contained in the vessel 18. The oil runs in upon the graphite and spreads over the latter, and when it reaches the wire-cloth 46 it will trickle down said cloth to the opening 19, where it will drip off drop by drop through the conduit 20 onto the journal 16,

it being understood that as the oil spreads over the graphite each drop of said oil will carry with it a portion or deposit of the graphite, whereby that lubricant which passes through the conduit 20 will be a composition of oil and graphite or their equivalents.

As has been remarked, the oil leaves the nozzle 27 in drops 51, which drops pass through the water 40 contained in the glass tube 28. In this way the speed with which the final discharge of the lubricant takes place can be ascertained by the rapidity with which these drops are being expelled from said nozzle through the water.

For the purpose of preventing too great a discharge of the lubricant I situate in the conduit 24 a valve 53, suitably held in place by a collar 54 and which is provided with a handle 55, and by this means the quantity of lubricant to be discharged may be arranged for.

For cleansing the chest, as well as the bore and tube, I may provide plugs 47 and 48, respectively, which may be suitably screwthreaded one into said chest and the other into said bore in a manner, for instance, as shown, and for cleansing the conduits 37 and 85 I may provideplugs 49 and 490, suitably `screw-threaded into said conduits, as shown.

The 'same structure as heretofore described and which embodies the reservoir 6, the glass tube 28, the extension 21, the chest,17, and the receptacle 18 is shown in Fig. 3, and it may embody all of the details of construction heretofore pointed out with reference to Figs. 1 and 2. l Instead,however, of being applied to a journal, as shown, for instance, in Fig. 2, the same is applied to a steam-pipe 60, connected with a valve-chest, (not shown,) and a lubricant-conduit 61 instead of being directed downwardly through the extension 14 is preferably directed along the longitudinal axis of said extension intovthe mouth of the pipe 60. Commu? nicating with such conduit 61 is a pipe 62, which is directed into the reservoir 6 in a manner similar to that heretofore explained, whereby steam may pass therethrough and be held in a condensed condition within the reservoir in the manner heretofore described. The two structures are practically similar, with the exception that the method of the application of the parts to be lubricated is somewhat different. Y

In Fig. 5 I illustrate another construction which may be used in connection with various parts to be lubricated, such as small journals, &c., and this construction discloses a reservoir 64, a receptacle 65, an intermediate connection 66, and av nozzle 67 for attaching the combined structure in place. The interior of the receptacle 65 may be provided with a wire-cloth lining or other open-mesh lining and also be illed with graphite or other suitable material 69.. The reservoir may be provided with a screw-threaded plug 70, through which maybe passed a stem 71,v having a screw-threaded head 72, fitted into `the screw-threaded opening 7 3 in the base of said lreservoir 64 and which head in the present instance may be provided with an oblique conduit. 75, through which the oil 76 in the reservoir 64 may drip into a chamber 77 and through a conduit 7 8 into the graphite 69, the extent to which said oil may drop being determined by the adjustment of the rod 71, preferably, and for observing the extent to which the oil is dropping on the graphite I provide a glass tube 79, carried by a connection 66 and which connection is provided with sights 80 and 81, respectively.

It will be observed that the pressure within the reservoir 6 is equalized by the steam-pressure which may be directed into the chest 17 through the conduits 36 and 37, connected to the conduit 35, and in this way the oil cannot run too fast into the graphite, and whereby pressure will be so directed onto the graphite as to prevent it from being lifted out of the receptacle by under pressure through the port 19.

It will now be observed that I- have provided a lubricating device for discharging a lubricant and combining it with another lubricant by an intermittent process and whereby the two lubricants are directed'to the-place to be lubricated in a compound or mixed condition. It will be further observed that I provide a method by which to determine the vamount-'of lubricant being utilized, also for controlling the amount to be utilized.

It will be noted that the introduction of oil into the graphite is not essential, it being understood that the graphite alone, being a lubricant, may be carried tothe parts to be lubricated by such other suitable medium as may be selected. V

Within the purview of this invention I may resort to various constructions or assemblage of parts of lubricating apparatusso long as I maintain the integrity of the principle of combining two or more lubricantsand. effecting such combination through means whereby both will becarried to the parts to be lubricated.
